The episode where Kenan finds a rat

The part where Kel says, "Hey rat, where you at in the store?" a woman hears him and says, "Did you say there's a rat?" then Kenan says, "No, that's not even close, the boy said 'cheer mat.'" As he says it, look at the shopping basket the woman is holding. It is green in her hand, then it goes to Kenan and back to the woman, and it is red. And when she puts in down to leave, it is green again. Weird, huh?
